This dataset consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in a farming area using eddy covariance techniques. The data were processed using PyFluxPro (v3.4.18) as described by Isaac et al. (2017). PyFluxPro produces a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).

The Myall Vale A site is located on a privately owned dryland field near Boggabri, New South Wales. The terrain is flat and elevation of the site is close to 240 meters above mean sea level. 
Credit
We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging. The site is managed by the CSIRO. 
Purpose
The purpose of the Myall Vale A Flux Station is to:
  • Develop and ground-truth the APSIM model.
  • Develop and ground-truth satellite based evapotranspiration models at pixel to catchment scale.
  • Complement and infill gaps in agricultural flux datasets in the treatments and locations being measured
  • Along with soil carbon and plant biomass data provide input for carbon balance research.
The station was commissioned on 15 November 2023 and is managed by CSIRO Environment.

Data Quality Assessment Scope
If the data quality is poor, the data is filled from alternative sources. Filled data can be identified by the Quality Controls flags in the dataset. Quality control checks include (i) range checks for plausible limits, (ii) spike detection, (iii) dependency on other variables and (iv) manual rejection of date ranges. Specific checks applied to the sonic and IRGA data include rejection of points based on the sonic and IRGA diagnostic values and on either automatic gain control (AGC) or CO2 and H2O signal strength, depending upon the configuration of the IRGA. For more details, refer to Isaac et al (2017) in the Publications section, https://doi.org/10.5194/bg-14-2903-2017.
